LBTEK's High-precision Optical Delay Lines kit consists of a Servo Linear Stage, a Servo Single-axis Controller, a Hollow Retroreflector Mirror, a Plano Metallic Mirror, an edge-free optical mount, and an adjustable iris diaphragm. The Hollow Retroreflector Mirror is assembled from three mutually perpendicular Plano Mirror, Back Side Polished units; a beam at any Incidence angle returns parallel along the Incidence direction, with a Deflection Angle of less than 20 arcsec. The stage carries the Retroreflectors in linear motion to achieve continuous variation of the Optical Path. The beam enters the optical reflection system through the system entrance pupil diaphragm, is folded by the Plano Metallic Mirror, then enters the Hollow Retroreflector Mirror, is reflected parallel back to the Incidence direction by the Retroreflectors, and finally passes through the exit pupil diaphragm to confirm the collimation and reliability of the Optical Path. During displacement, the Retroreflectors only translate and do not rotate; the output spot only translates while its direction remains unchanged, so long-time scanning requires no point-by-point realignment. LBTEK's High-precision Optical Delay Lines kit can achieve sub-fs (femtosecond)-level precise delay; the stage Resolution is 50 nm, and the single-pass delay step is approximately 0.667 fs. The stage uses a direct-drive brushless DC linear motor with no mechanical transmission components, eliminating backlash, and integrates an absolute linear optical encoder servo feedback system internally, enabling a minimum ±0.25 μm repeat positioning accuracy and a maximum speed of 500 mm/s. The kit is divided into single-pass and double-pass types according to the number of times the beam passes through the moving assembly, each providing 100 mm and 220 mm travel options; the delay ranges can reach 0–1467 ps and 0–2934 ps, respectively, and support two Retroreflectors coating options: UV-Enhanced Aluminum Coating 250 nm–600 nm and protected Silver Coating 480 nm–20.0 μm. In addition to the standard configuration of the Optical Delay Line kit, if the travel, configuration, or coating differs from existing models, LBTEK provides solutions customized to the actual Optical Path: provide parameters such as the required wavelength range, delay window, and installation space, and we can provide a corresponding solution accordingly. For specific customization and delivery Period, please contact customer service for confirmation.

LBTEK's High-precision Optical Delay Lines Kit (Single-pass) includes a Servo Linear Stage, a servo single-axis Controller, a Hollow Retroreflector Mirror, two Plano Metallic Mirrors, two edgeless optical mounts, two adjustable irises, and a Post Holder assembly. After the beam enters, it is folded by a Plano Mirror and directed into the Hollow Retroreflector Mirror, where it is reflected parallel to the Incidence direction by three mutually perpendicular reflective surfaces, then exits through the exit pupil iris; the change in Optical Path is twice the displacement. In addition, another iris included in the kit is provided for users to build an entrance pupil iris. The Motorized reflective assembly in the kit has travel ranges of 100 mm and 220 mm, with delay ranges up to 0~667 ps and 0~1467 ps; the stage Resolution is 50 nm, corresponding to a single-pass delay step of approximately 0.667 fs. The two adjustable irises provide a Clear Aperture with Continuous Adjustability over Ø1 mm~Ø12 mm, and are used to confirm Optical Path alignment and consistency of repeated setups; the Mounting Posts can slide within the Post Holder, allowing the Optical Axis Height to be Continuously Adjustable without replacing the Mounting Posts. The kit supports two optional Wavelength Ranges: UV-Enhanced Aluminum Coating, 250 nm-600 nm, and protected Silver Coating, 480 nm-20.0 μm. Note: the kit does not include a breadboard; if needed, it can be selected and purchased separately according to requirements.

LBTEK's High-precision Optical Delay Lines Kit (Double-Pass) adds an Optical Delay Line Plano Mirror, Back Side Polished Mount Assembly to the single-pass configuration. It includes a Servo Linear Stage, a Servo Single-Axis Controller, a Hollow Retroreflector Mirror, four Plano Metallic Mirrors, one right-angle dual-mirror assembly, two Clear Edge Optical Mounts, two Adjustable Iris Diaphragms, and a Post Holder Assembly. The two mounting surfaces of the right-angle dual-mirror assembly are machined into an orthogonal structure through Precision Machining, each mounted with one Plano Mirror, Back Side Polished. The Input Beam is reflected by the two surfaces and returns parallel to the original beam; the beam passes twice through the Hollow Retroreflector Mirror mounted on the stage, so the optical path length change is increased to four times the displacement. The Motorized reflection assembly has travel ranges of 100 mm and 220 mm, with delay ranges up to 0~1334 ps and 0~2934 ps; the stage Resolution is 50 nm, and the double-pass delay step is approximately 1.334 fs. The four mirrors use the same coating design, so after Multiple Reflections the loss of each wavelength component is consistent, introducing no additional spectral tilt. The kit supports two Wavelength Range options: UV-Enhanced Aluminum Coating 250 nm-600 nm and Protected Silver Coating 480 nm-20.0 μm. Note: The kit does not include a breadboard; if needed, it can be selected and purchased separately as required.
